Description

Parameter / Process	Specification & Technical Highlights	Advantage / Value
Material	Grade 316 Stainless Steel (CF8M / 1.4408)	Provides superior corrosion resistance (especially against chlorides) and high-temperature durability in petrochemical environments.
Unit Weight	9.86 kg	Balanced structural weight for heavy-duty, high-velocity industrial pump systems.
Flow Channel	6mm Narrow Flow Channel (Ultra-precise)	Designed for optimized fluid dynamics, maximizing pump efficiency while handling aggressive media.
Advanced Process	• Wax parts splicing • Complex inner cavity shell making • Difficult-to-dry geometry control	Mastery of high-difficulty lost wax casting to ensure seamless, obstacle-free internal fluid pathways.
Casting Tolerance	ISO 8062 (GB/T6414) CT6 Grade	Exceptional near-net-shape accuracy, reducing costly post-casting machining.
Balancing & Finish	• Dynamic Balance Test Required • Precision surface machining treatment	Eliminates vibration during high-speed rotation, extending equipment lifespan and bearing health.

To ensure maximum operational safety and flawless performance in petrochemical applications, we offer standard-compliant verification:

Dynamic Balancing Test: 100% verified to eliminate rotational imbalance, ensuring smooth and quiet pump operation at high RPMs.
Dimensional & Geometry Check: High-precision inspection via Coordinate Measuring Machines (CMM) to verify blade profile and complex internal structures against CAD data.
NDT & Material Inspection: Supported by Spectrometers for chemical analysis, hardness testers for mechanical properties, and Liquid Penetrant Testing (LPT) to detect any micro-defects.
Surface Treatment: Customized surface finishing (such as Passivation for enhanced anti-corrosion layer) available upon request.

Tailored Engineering: We specialize in custom impeller casting based on your 2D drawings or 3D files (STEP, IGES, DWG).
Full Traceability: Material certificates and complete quality inspection reports (including dynamic balance data) are provided with every batch.
